LUBRICATE the inner- analog stick

Hi,

So I recognized that my 3ds analog stick moves less smooth than usual,

my 3ds was pre ordered when he was announced and I actual decided to get a

new one.

But as long as i don`t have the money, I want my old one to function.

I opened him already, without damage, a little while ago, trying to clean the (socket)

of the analog stick and stuff like hairs was in there ( cats ).

I cleaned it, but its not much better. So i thought, maybe there is a special liquit for such sensitive electronic devices and I want to know it by the professionals.

And thanks for this forum :), I´ll wait.
